SUMMARY

In August 2007 and 2011 we mapped by helicopter different Peat Swamp Forest (PSF) transects with Riegl LiDAR Technology (LMS-Q560) and high-resolution Hasselblad camera in Central Kalimantan, Indonesia. Pairwise comparisons of nearly coincident LiDAR footprints at the Sabangau transect (e.g. 14km) over a period of four years showed canopy height changes up to 12%. On average, the canopy height increased from 15.32m to 17.18m. Additionally, we measured biomass growth with the LiDAR change detection method and subsidence of open degraded peatland. This work could be promising in the framework of the REDD+ (Reducing Emissions from Deforestation and forest Degradation) knowledge of tropical PSF. The LiDAR technology supports the MRV aspect of REDD+ (Monitoring, Reporting, Verification).
